We studied the effects of marine protected areas (MPAs) on predatory interactions at a regional scale of 3 different islands across the geographical gradient of the Canary Islands. Protection measures positively affected predatory fish assemblages, enhancing the intensity of predatory interactions in comparison to equivalent unprotected areas (UAs), and causing indirect effects on populations o...

Authors face many choices when selecting a journal for publication. Prospective authors, especially trainees, may be unaware of "predatory" online journals or how to differentiate them from legitimate journals. In this study, we assessed awareness of open-access and predatory journals among prospective authors attending scientific writing workshops; our long-term goal was to inform educational ...

Predatory publishers solicit manuscripts through e-mail invitations to potential authors, with the goal of enticing authors to submit a manuscript to the journal. This descriptive study examined the characteristics of 206 e-mail invitations from predatory journals and publishers sent to faculty and students in a school of nursing over a 10-week period. Characteristics of these e-mails included ...

Lesions in ventromedial part of amygdala impaired neither alimentary instrumental reflexes nor food intake, but impaired predatory behavior. Lesions localized in the more dorsal and lateral part of the amygdala produced disorders in instrumental performance and food intake without changes in predatory attack. Both kind of lesions did not impair neurological reflexes, therefore the abolishment o...

Social dominance in predatory animals was tested before and after amygdala lesions. Cats after damage of dorsal part of amygdala did not show predatory behavior in group and lost their social rank in hierarchy, but in the same animals predatory attack remained unchanged in nonsocial situations. In the cat with medial amygdala lesions total abolishment of mouse-killing behavior was observed in b...

although host plant resistance is the healthiest, most reliable and cheapest way of pest control, to achieve a successful integrated pest management, pest-resistant plant varieties should be compatibity with the biological control agents. throughout the present study, the performance of the predatory mite, phytoseiulus persimilis، on four common bean cultivars (naz, khomein, akhtar and g11867) ...

During the last decades, non-native predatory fish species have been largely introduced in European lakes and rivers, calling for detailed information on the trophic ecology of co-existing native and non-native predators. The present study describes the trophic ecology of the introduced pikeperch (Sander lucioperca) in two southwestern French rivers, using stable isotope analysis. Pikeperch cou...

Predatory pricing—a deliberate strategy of pricing aggressively in order to eliminate competitors—is one of the more contentious areas of antitrust policy and its existence and efficacy are widely debated. The purpose of this paper is to formally characterizes predatory pricing in a modern industry dynamics framework. We endogenize competitive advantage and industry structure through learning-b...

BACKGROUND The Internet has transformed scholarly publishing, most notably, by the introduction of open access publishing. Recently, there has been a rise of online journals characterized as 'predatory', which actively solicit manuscripts and charge publications fees without providing robust peer review and editorial services. We carried out a cross-sectional comparison of characteristics of po...
